Application filed March 12, 1926. Serial No. 94,222.

My present invention relates to improvements 1n shockers for use 1n connection with binders of harvesting machines.

in the sheaf or bundle is received from the binder in horizontal position and then turned and manipulated by automatic means to an upright position with its butt end below and in this latter position the sheaf is conveyed to the shock'former or platform from which it is discharged through the operation of mechanism manually controlled., Automatic means are provided for laterally swinging the sheafconveyers in order that they may distribute the sheaves to alternate'sides of the center of the shock former or platform.

'In the present exemplification of theinvention I have illustrated the driving mechanism of the shocker as actuated with power from a traction wheel of the machine, and the sheaf receiving mechanism which receives the sheaf from the binder, is controlled by the weight of a sheaf whereby the load imposed'upon the receiving mech anism moves the latter to position for cou pling with the driving mechanlsm,

The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully set forth and In the accompanying drawings I have illustrated one complete exampleof the phys ical embodiment of my invention wherein the parts are combined and arranged in accord with the best mode I have thus far devised forthe practical application of the principles of my invention,

Figure 1 is a plan view of a shocker embodying my invention showing a portion of the binder at one side thereof from which the sheaves or bundles are received. 1 Figure 2 is an enlarged, outer side elevation of the machine.

I v 1 Figure Tis a detail view of the manually controlled operating parts for the shockformer.

I In carrying out my invention I utilize the usual ty )e of main frame 1 for shockers and utilize t e front traction wheel 2 as the power wheel for the machine, the rear end of the machine being supported by caster wheels as 3, A portion of the binder is shown at 4 with an inclined chute 5which delivers the sheaf indicated in dotted lines.

in'Figures 1, 3 and 5, by the letter S.

The sheaf is delivered. to the shocker in v longitudinal or horizontal position-and is received from the lower free endof the chute 5 is a concavo-convex trough '6 which is located at the approximate longitudinal center of the machine,,and*as indicated by full lines in Figures 2 and 3 normally rests at a slight inclination above the curved floor-pan 7 of the shocker. e

This receiving trough performs'the function of a rotary carrier forthesheaves as they are successively received from the binder -chute and it is provided with spokes 8 that radiate from a hub 9 on the carrier.

shaft 10 which is journaled at'the outer side and transversely of the shocker in bearings I 11 on a suitable frame. i The rotary carrier 1 is designed to make one complete revolution with its shaftltl inthe manipulation of asheaf and theshaft is provided witha mutilated gear 12 which is brought to. op-

erative position and coupled with the drivmg mechanlsm by an initial swingingmovement of the carrier which movement is caused by the weight of the sheaf when the latter is deposited A in the empty carrier. lVhen the weight of the sheaf swings the carrier the shaft 10 and mutilated gear 12 are turned to bring the latter into mesh with an idler pinion 13 on a stub-shafte13 and the idler is driven from the pinion 14 onathe operating. shaft 14. The operating shaft 1-1 is driven from a drive sprocket wheel 15 on the axle 16 of the traction 'wheel 2, and the chai1i17 from this sprocket wheel passes over a sprocket 18' on the operating shaft 14, to drive the machine parts.

Thus the sheaf is deposited in the rotary carrier with its butt end to the right or front in Figure 2 and the carrier is given a completerevolutionclockwise to deliver the sheaf in standing position-on its butt end.

As thecarrier turns the sheaf a tangentially arranged guide frame 19 of the carrier guides the sheaf as it is delivered in standing position between the two guidewails or plates 20 and 21 that extend longitudinally of the machine and are spaced at opposite sides of its longitudinal center at the rear of the rotary carrier. The sheaves pass through or between these guide walls as indicated by dotted lines in Figure 3 under succe sive operations of the rotarycarrier and are thus passed into the front openings bet cen a pair of endlesscanvas belts 22 and 223 which form the conveyer for the sheaves from the rotary carrier to the shock former. The endless belts of the conveyer stand in up right position and extend longitudinally of the machine, therear ends of the belts being free-to swing at their lO*""l edges later ally of the machine to distribute the sheaves at alternate sides-of the longitudinal (as; r of the machine.

Each belt passes arounda pair of vertically-disposed rollers El and 25 and the four rollers are provided with shafts and 27, 27. The'shafts are journuled at ii ir upper and'lower cnds'inpairsof extensible frames, andthese extensible frames are made up of alined bearin'g'bars 28 and 2!) that are coupled together by means of a nut 30. The two shafts 2i and ili" have station 'ary bearings or supports 31 through which bearing frames and ti ese two shafts are used 7 as pivots to swing laterally the rear ends of the respective frames and thus swing the two rollers '24 laterally over the deck of'the shocker. The upperends-of an the shafts 'remain stationary while the lower ends of the two shafts-2G '26 swing laterally and thus swing their belts. Two transversely disposed arch bars 32 and 33 retain the upperends of'the shafts a ainst lateral movement. cured to the-deck of the shocker-and the bars are perforated to accommodate the shafts. The shafts 26 andQG fitloosely in the perforated arch bar 32 and cotterpins 34 "passed transversely through the shafts above the bar permit the necessary loose ll'lOVGTllGllhat the upper ends of these shafts asthe oonveyer belts swing, as'indicated in Figurel and'also in Figure 5.

The swinging movement of the conveyor on theshafts 26 and 26" as'pivots is accomplished through two arms 35 and 36 attached to the undersi'des of the 'lower e: ;tensible-brace bars-ofthe rollerframes, which arms have ho'les through which the shafts pass and to permit-the arms to oscillate on the shafts. The arms extend longitudinally of the shock er and at their free ends are loosely pivoted on a cross link 37 that extends toward. the outer side of the shocker machine. A pitman 38 is connected to the link and to an The ends of the bars are se-.

eccentric disk 39 on the eccentric shaft 40 which is journaled longitudinally of the machine beneaththe main frame and provided with a sprocket all over which a chain 42 passes from a drive sprocket on the operating shaft 10 of the carrier in order that the rotary carrier and the distributing conveyor quay operate in unison.

The shafts 20 and 26 form the drive shafts for the convcyer belts which are operated from the operating shaft it through a sprocket l-lon this shaft, a chain and a sprocket wheel 46 on 'the'transversely disposed countershaft l7. Bevel-gear couples and it) between the counter-shaft l7 and he respective shafts 26 and E26 transmit power from the'trai'isverse shaft to the vertical shafts. a

The shock former is located at the rear of the machine in position to "receive the inwardly to retain the shock as it is being formed, and these walls'have cross flan cs 5f atthe rear, which are elevated above the platforms as indicated in Figure Each section of "the laterally -opening shock former is provided with a pail-of spaced, transversely extending rack bars as and 56 that extend outwardly fromt-h'e longitudinal center of the machine and are adapted to slide in the guideplates oo se cured to the main frame of the machine. Each sectionis actuated by *apair of-pinions as 57 and 58lhat co=act with the rack bars and'these pinions arefixed t0 revolve with a pair of longitudinally disposed shafts 59 and 60 journaled in suitable bearings near the sides of the frame at the rear and revolved from a single crossshaft 61 through two bevel-gear couples 62 and 63.

The openingand'closing movements of the sections of the shock former are manually controlled from the inner side ofthe vmachine by the use of belts and pulleys located between-theshaft 4-7'and the-shaft 61; A pulley 64 on the end of the shaft Manda pulley 65 on theend of the shaft 'tll are coupled together by theloose belt' 66 asrincheated in Figure E and" a second loosebelt ('37 which is crossed is suspended between pulleys 68 and 69 on these shafts. Normally the belts do not transmit rotary motion from one shaft to the other, but belt tighteners I are employed and alternately used for causin the movements of the sections.

lo discharge the completed shock an idle roller 70 011 the pivoted arm 71 is caused to 'After the shock has been discharged the sections are closed together by operating the .belt tightener for the belt 66 which comprises an idler roller 72 on the pivoted arm 74, and the pull wire or rod 75. The crossed belt imparts a reversed movement to the transverse shaft 61 and the longitudinal shafts 59 and 60 causing the pinions in cooperation with the rack bars to slide thesections together against to normal posit-ion as indicated in Figure 5. v I
